Niacinimide ●
TL;DR. It is a water-soluble cosmetic active used for skin conditioning, barrier support, visible tone evenness, and the look of excess oil control. In formulas, it is an active ingredient rather than a preservative, emulsifier, or fragrance component.
What does Niacinimide do in a cosmetic formula?
It is a water-soluble cosmetic active used for skin conditioning, barrier support, visible tone evenness, and the look of excess oil control. In formulas, it is an active ingredient rather than a preservative, emulsifier, or fragrance component.
Is Niacinimide clean?
It has strong clean-standard standing, with low sensitization potential and no common restricted-list issue at typical cosmetic levels. Some users may notice transient warmth or flushing at higher levels or in very acidic formulas, where conversion to a related acid can increase irritation potential.
Is Niacinimide sustainable?
This ingredient is typically made by controlled fermentation or chemical synthesis from simple feedstocks, rather than by extraction from scarce botanical sources. It is water soluble, readily biodegradable, and not known for environmental persistence or bioaccumulation concerns.
Is Niacinimide COSMOS-approved?
It is generally permitted under COSMOS-natural and COSMOS-organic when it meets the standard’s purity, sourcing, and processing requirements. From a Green Chemistry view, it aligns well on low use level, biodegradability, and efficient manufacture, though renewable feedstock depends on the supplier route.
How does Niacinimide work chemically?
The molecule is a small, water-soluble heteroaromatic amide that is typically used around 2% to 5%, with some formulas going up to about 10%. It is most stable around pH 5 to 7, and formulators usually limit very acidic conditions, prolonged heat, and incompatible low-pH systems to preserve comfort and stability.
